AGGREGATE DRYING/HEATING DEVICE AND AGGREGATE DRYING/HEATING METHOD FOR ASPHALT PLANT

摘要

PROBLEM TO BE SOLVED: To prevent a peripheral environment from being destroyed or contaminated when aggregate is dried and heated, and to prevent vibration and noise from being generated when the aggregate is dried and heated.;SOLUTION: A conveying device 35 conveying the aggregate 53 at a speed corresponding to a drying/heating time is disposed in a drying/heating furnace 31. An electromagnetic wave absorbent body 45 is installed in the drying/heating furnace 31, and high-frequency electromagnetic wave is outputted from a high-frequency oscillator 41 to the electromagnetic wave absorbent body 45. The inside of the drying/heating furnace 31 is heated to a specified temperature by absorbing the high-frequency electromagnetic wave outputted from the high-frequency wave oscillator 41 to the electromagnetic wave absorbent body 45 for heating so as to dry and heat the aggregate 53 conveyed by the conveying device 35.;COPYRIGHT: (C)2007,JPO&INPIT
